Primary MALT lymphoma mostly occurs in the stomach and rarely arises from the duodenum. Our patient had a firm, well-circumscribed, duodenal mass centered within the submucosa that extended into the mucosa, causing a 4 x 2-cm ulceration, diagnosed as MALT lymphoma.

Our case is one of few reports of pyogenic granuloma in the large intestine, and shows typical patterns of a macroscopically possible malignant tumor presented in a relapsing manner that was successfully treated with snare polypectomy after submucosal injection.

Von Meyenburg complexes are non-hereditary bile duct malformations that originate in the peripheral biliary tree, and may occur within the context of polycystic liver disease. Liver ultrasound imaging may show the “comet tail” sign.

We present a case of a 48-year-old woman with HCV-related cirrhosis who presented with severe generalized plaque-like pruritic rash over a period of 2 weeks attributed to telaprevir (TVR)-based triple therapy.

A 66-year-old male was referred for the treatment of a polyp extending into a diverticulum. Endoscopic band ligation (EBL) was used to resolve the diverticulum. Residual small polypoid lesions were resected using endoscopic mucosal resection (EMR), and no complications occurred after treatment.

A 50-year-old man with a history of epilepsy controlled with phenytoin taken daily without water and severe stricturing of the mid-esophagus. Biopsies were consistent with a drug-induced injury with lymphocytic infiltration and epithelial cell necrosis.

We report a case of a gastric duplication cysts adjacent to the pancreas with high cystic fluid amylase and carcinoembryonic antigen (CEA) and 3 different epithelia (respiratory, gastric, and intestinal), all diagnosed via endoscopic ultrasound with fine-needle aspiration.

Portal hypertension leading to gastric polyposis has rarely been reported. We report a case of a patient in whom portal hypertension manifested as bleeding gastric polyps leading to transfusion-dependent iron deficiency anemia.

We present the case of a 71-year-old female with severe enteropathy attributed to celiac disease for 5 years that improved only after valsartan cessation. This is the first case associating valsartan with sprue-like enteropathy.

A 67-year-old woman with a 15-year history of intestinal scleroderma presented with recurrent melena attributed to a splenic artery pseudoaneurysm adjacent to a gastric ulcer. This is the first reported case of gastrointestinal bleeding from a splenic artery pseudoaneurysm in a patient with intestinal scleroderma and a large gastric ulcer.

A 20-year-old male underwent TIPS placement, but soon after had mild left intrahepatic biliary dilatation without stones or obvious stricture. Endoscopic retrograde cholangiopancreatography (ERCP) demonstrated a focal stricture due to compression by the TIPS.

A 53-year-old male presented with a small fistula between the proximal biliary tree/porta hepatis and the duodenal bulb, likely secondary to previous chemotherapy and radiation. A stent was placed in this fistula, as this was the only pathway available for biliary drainage.

We report a challenging case of systemic diffuse large B-cell lymphoma (DLBCL) that initially presented with septic shock from acalculous cholecystitis. After extensive investigation, DLBCL was found to be the underlying cause of gallbladder disease.

We present a case report of an 80-year-old woman with volume overload thought initially to be secondary to heart failure, but determined to be amiodarone-induced acute and chronic liver injury leading to submassive necrosis and bridging fibrosis consistent with early cirrhosis.

A 66-year-old man with HIV and recurrent thromboembolism presented with non-cirrhotic portal hypertension. The etiology of portal hypertension was attributed to didanosine therapy, a rare but noted side effect.

Refractory celiac disease (RCD) is a rare but life-threatening complication of celiac disease (CD), and only 1 pediatric case has been reported. We report a case of a 14-year-old girl diagnosed with RCD and treated with infliximab with subsequent complete serological and histological remission.
